Sometimes it’s the things we don’t see that matter most. Connected by a shared passion for the ocean and a desire to protect it, Belinda Baggs, Kimi Werner and Wayne Lynch embarked on a sailing journey along Australia’s Great Barrier Reef. The largest living structure on earth, the reef provides habitats for thousands of species. The reef, however, is under threat. Currently almost half of its coral has been lost or damaged, most of this in some way attributable to human impact, the biggest single factor being climate change. The three sailors explored the reef and experienced personally how something as vast and wonderful as the Great Barrier Reef can at the same time be entirely vulnerable, realizing as they sailed and swam that time is fast running out to save it.
